Stock 4AGZE pistons in 7A block will give you 10.8 CR (Edo got 11.06 cuz of the Bigger bore), so then using 1.5 mm head gasked you will get the CR between 9.5-9.6 and using 2mm head gasket will get you at 9-9.1 CR.
you have three options on aftermarket rods ARGO, PUATER, OR CUSTOM 700+ at min

ok this is a little off topic but I’m getting to the point where I’m going to start reassemble now you know doggy 4agze head and pistons 8.0:1 can I just the stock height gasket and will my comp change?

i was just tryint to find this info my self too.. i dont know about the CR with the Gze piostons and GE head.. Need to do a research on Club4AG there was few topics there i go the info about CR..




By the way, if some one could recalculate the CR for 7A with GZE pistons, here are the info:

Bore 81
Stroke 85.5

Cumbusion chamber volume - 36 cc (head)
Dished piston volume 10 cc

7A pistons are dished, as 4AGZE pistons are almost flat...
